specification of Letters Patent. Patented May 17, 1921,

Application filed August 9, 1918. Serial No. 249,083.

To all whom it may concern: Be it known that I, ERVAN V. ALLEN, a citizen of the United States, residing at Bogalusa, in the county of Washington and State of Louisiana, have invented certaln new and useful Improvements in Cultivators; and I do hereby declare the following to be a full,;clear, and exact descrlption of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. a

The object of the invention is to provlde a relatively inexpensive and eflicie lt cultl vator: construction having a framework made up essentially of metal while havlng the maximum strength with the minimum weight to insure durability while imposing the least possible effort and strain upon the operator in guiding or directing the same while in use; and furthermore to provide an apparatus for the purpose indicated with reference to which a relatively wide range of cultivating shovels may be used, so as to extend the utility of the device to meet the various needs of the farmer.

Further objects and advantages will appear in the following description, it being understood that changes in the form, proportion and details of the illustrated embodiment of the invention may be resorted to, within the scope of the appended claim, without departing from the spirit of the invention.

In the drawing:

Figure 1 is a side view of a cultivator constructed in accordance with the invention,

Fig. 2 is'a plan view of the same,

Fig. 3 is a transverse section on the line 33 of Fig. 1,

Fig. 4 is a horizontal sectional view. on the plane indicated by the line 44 of Fig. 1, I

Fig. 5 is a transverse sectional vlew on the plane indicated by the line 5 5 of Fig. 1,

Fig. 6 is a front View of the forward shovel and standard. 7

The structure illustrated embodies essentially the main central longitudinal beam 10, to the forward end of which is attached the draft appliance 11, the rearwardly d1- vergent relatively adjustableside beams 12, which carry the plow standards 13and are connected pivotally at their forward ends to the beam, and a transverse adjustable or PATENT OFFICE.

ible connectionv ii between the-rear ends of said side beams and themain beam,

and handles 15, which are supported at intermediate points by braces 16 from the main beam and, are attached at their forward ends .to the upper extension of a standard vl7, which supports the forward support ngwheel 18. Themain beam preferably consists of parallel metallic bars 10 aboveementioned' standard 17, Y and a standard19 of the rear supporting and guiding wheel, 20, aspacing block 21 being. interposed between said barsat their rear extremities, a forward standard 22 being interp'osed therebetweenj near their forward ends, and a draft bar or tongue 23 beinginterposed'between and secured to the same in advance of the standard 22, and having the above mentioned-draft appliance 11 carrled thereby. Supported by said parallel bars or elements 10'" and 1t) of the main beam are the upper and lower plates 24:

secured by vertical bolts 25, and connected by bolts or plns 26 engaging lateral extensions of the plates to form fulcrums for the side beams 12, which also consist of parallel bars or elements 12 and 12 which may be connected at their forward ends by loops 27 which in the construction illustrated are formed as'integ'ral parts of the elements 12 and 12 to engage pivotally the portions of the bolts 26 between the planes of the parallel plates 24. The plow standards 13 are interposed, at intervals between the elements of the side beams, and said. elements are connected at intervals by transverse bolts 28, the tightening of which serves to draw the elements into frictional engagement with, the interposed standards, and upper and lower front and rear bearing polnts or projections 29 and 30 may be provided on said side beam elements to enproper adjusted position.

ards, any desired form of shovels maybe used ln'this connection, as for example the diamond shaped blade 32, which is attached It will be understood that while turning. I shovels 31 are shown attached to said stand- 3 I Spacing blocks 33 may be interposed between the rear ends of the elements form- 1 65 and 10 spaced laterally to receive the as shown at 35, for engagement by the locking bolt 36 to maintain the elements in their adjusted relation and thus hold the side shovel-carrying beams in the desired rearwardly divergent positions with reference to the main or central beam.

The advantages in operation of a structure such as above described will be apparent to those skilled in the art, and particularly those engaged in the operation of devices of this character and to the manufacturer it will be equally obvious that the various members maybe constructed with a minimum of mill work and by the use of tools ordinarily employed, machining being reduced to the minimum while the resulting structure, which is comparatively light in weight has its parts so disposed as to afford themaximum strength and resistance to the strains to which devices of this character are ordinarily subjected. The reshovels of different kinds or designed for main and side beams and the connections between the same and including the transverse adjustable bar and the braces for the handles are of stock form, or may readily be produced from sheet or plate metal of the selected gage and may be adapted to the various purposes indicated with a minimum shaping or other treatment.

Having described the invention, I claim:

In a cultivator, a 'beam composed of spaced side bars, said side bars beingprovided at their edges with incisions and the material of the side bars adjacent the incisions being inwardly disposed to form tongues which lie between the side bars, standards lying between the side bars and between the tongues carried by the side bars and soil engaging elements carried by k the-standards.

In testimony whereof I aflix'my signature in presence of two witnesses. ERVAN V. ALLEN. Witnesses: V
